The purpose of this utility model is achieved in that a kind of suspension thrust-bearing, it is characterized in that the magnetic shielding outer cover is a cylindrical tube shape, lower ending opening, there is axis hole the intermediate portion, upper end, at the inboard fixedly connected magnetic shielding dish of opening, the outside is connected with magnetic shielding outer cover adpting flange, connect magnetostatic power dish at magnetic shielding outer cover internal fixation, magnetostatic power dish is connected with moving magnetic force disk activity, there is axis hole moving magnetic force dish and magnetostatic power dish intermediate portion, the moving fixedly connected rotating shaft of magnetic force dish, magnetostatic power disk activity connects rotating shaft, the rotating shaft two ends are passed seal ring and are flexibly connected with magnetic shielding dish and magnetic shielding outer cover respectively, and each fixedlys connected a circular ring magnet in moving magnetic force dish and end face that magnetostatic power dish joins.
Preferred embodiment of the utility model is: the magnetic shielding housing opening is downward, magnetostatic power dish is fixedly connected on the magnetic shielding dish, moving magnetic force dish be positioned at magnetostatic power dish directly over, moving magnetic force dish and magnetostatic power dish are inlaid with circular ring magnet respectively, and circular ring magnet is an identical concentric pole magnet of the same race.
Another embodiment of the present utility model is: the magnetic shielding housing opening is downward, magnetostatic power dish is fixedly connected on the inner upper end face of magnetic shielding outer cover, moving magnetic force dish be positioned at magnetostatic power dish under, moving magnetic force dish and magnetostatic power dish are inlaid with circular ring magnet respectively, and circular ring magnet is identical concentric xenogenesis pole magnet.
The utility model compared with prior art has the following advantages:
Because having adopted the magnetic shielding outer cover is cylindrical tube shape, lower ending opening, there is axis hole the intermediate portion, upper end, inboard fixedly connected magnetic shielding dish at opening, the outside is connected with magnetic shielding outer cover adpting flange, connect magnetostatic power dish at magnetic shielding outer cover internal fixation, magnetostatic power dish is connected with moving magnetic force disk activity, there is axis hole moving magnetic force dish and magnetostatic power dish intermediate portion, the moving fixedly connected rotating shaft of magnetic force dish, magnetostatic power disk activity connects rotating shaft, the rotating shaft two ends are passed seal ring and are flexibly connected with magnetic shielding dish and magnetic shielding outer cover respectively, each fixedlys connected the structural type of a circular ring magnet in moving magnetic force dish and end face that magnetostatic power dish joins, thereby make moving magnetic force dish be able to get up to be close to no frictional rotation at the effect low suspension of permanent magnetism power together with rotating shaft, this bearing can keep the zero energy consumption operation of high rotating speed for a long time under high and low temperature environment, it is big that it has the axial force of bearing, suspending power is adjustable, the limit speed height, no frictional resistance, low energy consumption, noise free, non-maintaining, be applicable to advantages such as rugged environment such as high low temperature and long service life; Can be widely used in industries such as centrifuge, motor, submersible pump, deep-well pump, aircraft and screw propellor for boat, large-scale hydroelectric generator, steam turbine.
